[AZ-557] Fix MfaLoginTests AC1/AC2/AC7 seed ordering

UserService.ValidateUser calls RegisterSuccessfulLogin on a successful
password verify, which resets FailedLoginCount=0 even on the MFA path
(the reset happens inside ValidateUser before the MFA branch returns
the step-1 token). Seeding the counter before /login was therefore a
no-op — the threshold-1 seed was wiped before the wrong-TOTP request
got a chance to trip the lockout.

Move SetLockoutUntil to AFTER step 1 succeeds in AC1, AC2, AC7. AC7
now also genuinely exercises MfaService's own counter reset on a
correct TOTP, instead of being satisfied by the password-success reset.
